You'd be comfortable but i think it's misleading to think you're "very" well off. Assuming you live on your own with a mortgage.
As mentioned above the take home is just under £3k, assume 1k for a mortgage on an average house, then another £400 on council tax, utilities, etc. You're then just over £1500. Knock off another £300 for car insurance, car repayments etc and you're at around £1200 or £300 a week.
It's a decent chunk of money, but once you start wanting to put money away into savings, go on holidays, make home improvements, buy luxury items etc it runs out very quickly, especially when you can easily spend £100 on a night out.
It's a comfortable living where you're not panicing about money, but it's not some golden level where you can do anything you want without thinking.
